United States Patent 3,024,487 MULTIPURPOSE SCRUBBER Reginald H. Jonesand George W. Kane, Jr., Henderson, NC.

Filed Ap 25, 1960, Ser. No. 24,413 2 Claims. (Cl. 15-524) This inventionrelates to the cleaning of walls and floors of various types of materialincluding wood, masonry, tile and the like, and to equipment by whichwater and cleaning solution can be applied and the surfaces scrubbed toclean the same.

The invention relates particularly to a multipurpose brush or scrubberwhich can be attached to a conventional hose and to the provision ofmeans for supplying a cleaning solution to such brush or scrubber and bywhich cleaning solution and water can be supplied and the surfacesscrubbed to clean the same.

In the construction industry walls and floors are scrubbed with stiffbrushes by hand, such brushes being periodically dipped in a cleaningsolution and water is discharged onto the area being cleaned. Thisoperation is laborious, time consuming and requires excessive manpower.

It is an object of the invention to streamline the process of Washing byproviding a relatively simple and inexpensive multipurpose scrubber inwhich the water hose, the hose for the cleaning solution and the brushare combined in a single unit which can be readily operated by a singleindividual performing the washing operation efliciently and in a minimumof time.

Another object of the invention is to provide a multipurpose scrubberincluding a source of supply for a cleaning solution under pressure, adischarge hose, a spray nozzle, a brush in operative proximity to thelatter, and means for controlling the cleaning solution and water aswell as provision of a handle for guiding and operating the brush.

Other objects and advantages of the invention will be apparent from thefollowing description taken in conjunction with the accompanying drawingwherein:

FIG. 1 is a perspective illustrating one application of the invention;

FIG. 2, a similar view of reduced size with a hose for cleaningsolution;

FIG. 3, a section on the line 3 3 of FIG. 1; and

FIG. 4, a perspective of a spring clip for holding certain of the partsin assembled relation.

Briefly stated, the invention comprises a handle in the form of arelatively rigid pipe with a portion bent angularly and adapted to havea brush clamped thereon, the pipe having a connection at one end forattachment to a water hose and a laterally disposed discharge slotadjacent its opposite end through which water can be discharged subjectto a lever operated control valve adjacent the Water hose connection. Abrush is mounted in operative relation to the discharge slot in thepipe, the mounting being in any desired manner as, for example, by aU-clamp extending around the angular portion of the handle forming pipe.The angular portion of the pipe is for the convenience of the operatorto permit the brush to be used on upright walls, horizontal floors orsurfaces of other angles. 'If desired, a cleaning solution underpressure may be provided from a source of supply through a hose and adischarge pipe with a control valve for controlling discharge through anozzle on the outer end of the same, which nozzle is fixed to the handleforming pipe by means of a spring clip. Thus an operator by gripping thehandle forming pipe can scrub a wall, floor or other surface applyingcleaning solution to such surface and then flushing such surface withwater.

With continued reference to the drawing, a handle 3,024,487 PatentedMar. 13, 1962 forming relatively rigid pipe 10 has an angular portion11, such pipe having external screw threads 12 and 13 on its rear andforward ends respectively and an internally threaded cap 14 engaged withthe threads 13 to form a closure for the end of the pipe.

The pipe is provided at its forward end with a spray orifice in the formof a laterally disposed slot 15 through which water under pressure maybe sprayed at right angles to the axis of the angular portion 11 of thepipe.

In order to scrub the surface on which the water is sprayed through theslot or orifice 15, a brush 16 is provided, such brush having a back 17attached to the same by means of spaced screws 18, such back being inthe form of a hollow shell having a pair of openings 19 through whichare received the externally threaded ends 20 of a U-clamp 21, suchthreaded ends receiving thereon a pair of washers 22 and nuts 23 forfastening the U- clamp in position about the angular portion 11 of thehandle forming pipe and against an intermediate saddle member or wedge24.

By gripping the handle forming pipe 10 the brush may be applied to thesurface to be cleaned and water may be supplied to such surface throughthe pipe 10 from a source of supply such as a hose 25 and a coupling 26attached to the threaded end of a nipple 27 connected to a valve 28,flow through which is controlled by an operating lever 29.

In order to supply cleaning solution a tube 30 may extend to a containerfor such solution under pressure with such tube connected by a coupling31 with an externally threaded end of a nipple or short pipe section 32,the other threaded end of which is connected to a valve 33 subject to acontrol lever 34 for controlling fluid through a tube 35 and a spraynozzle 36 attached to the outer end of the handle forming pipe 10 bymeans of a spring clip 37, the pipe 35 also being fastened to the handleforming pipe 10 by means of one or more spring clips or clamps 38.

It will be apparent from the foregoing that a device is provided bywhich floors and walls can be readily cleaned including by scrubbing, bythe application of a cleaning solution, and clear water flushing. Itwill also be readily understood that the device can be readily used andthe operation easily accomplished by a lone workman with a minimum ofeffort and in a minimum of time.

It will be obvious to those skilled in the art that various changes maybe made in the invention without departing from the spirit and scopethereof and therefore the invention is not limited by that which isillustrated in the drawing and described in the specification, but onlyas indicated in the accompanying claims.

What is claimed is:

1. A multipurpose scrubber comprising an elongated pipe forming a hollowhandle, said pipe having a bend near one end whereby the end portion ofthe pipe is disposed less than degrees from the main portion of the pipeand with such end portion having a lateral orifice through which watercan be discharged onto a surface to be cleaned, a scrub brush, agenerally U-shaped clamp fastening said brush to said pipe forlongitudinal and to tational adjustment, and means for supplying liquidfor cleaning through said pipe and for controlling subject to the actionof the operator the flow through said pipe.

2. The structure of claim 1 having an additional line for the supply ofcleaning solution carried by said pipe on said hollow handle and havinga discharge nozzle adjacent said scrub brush whereby both water andcleaning solution can be supplied during the use of said brush.
